This apparatus is composed of :a :base 1 upon which :are :two standards 2 spaced from each other and reinforced at their baseby foundations ,3. base 1 has suitable holes forifixing it by means: of bolts .upon a .suitable-counter, :tableor furniture.

The; base :1 :shows vertically beneath the slidfable; frame 4, 5,-a circular opening 14uponwhich :fits. a funneFShaped: open base -15 provided with a vertical flange to "which is #fixed by means of screws 16 the stationary portion of acylindrical cover whorizontally divided into two halves, =1? and 18i.connected together by means of flanges -1 and 1-8 at-their adjacent *edgeswhich are secured :to- :each-otherby *means of bolts {19, the

The :bracketsi23 and.;24 .proj ect beyond the cylindrical rcover .11 7 and they :are jprovided "with evertical flanges-2-3f :andf24 which serve to fix them by (means of screws 1 to the standards 2 through a suitable slot:inthe-respective =column '4. rWithin :the-hollow bracketiwi-isrrotatorily mounted ahorizontal shaft :26 providedwithin the casing 25 with o a bevelled pinionz'lmeshing with. another'bevelled pinion-28 slidablyrcarried byr'means ofa-wedge 29 ;on--a verticaL-shaft 30: rotatoril-ysmount'ed in jour- :nal bearingsJ-iorined-at the upper and-lowerzpor- *rtionsof the --:casing 25 so that a the shaft .30 :can

slide under the pinion :28without this pinion 28 aused for sextracting theimilkiofutheicocoanut 84.

The shaft 30 may be lifted or let down by means of a cam 36 fixed at the end of a horizontal shaft 37 rotatorily mounted on a bracket 38 integrally formed at the top of the casing 25 and through an opening formed in the cylindrical cover 17, said shaft 37 ending outside this cover in a handle 38 for its operation, as shown in- Fig. 3 of the drawing. The bottom of the head 32 rests on the cam 36 and when the latter is rotated along with the.

shaft 37, it causes the head 32 to lift and with the same is lifted the slidable shaft 30. for the purpose explained hereinafter. The shaft 26 is coupled to any power producing means as the shaft of an electric motor or to a shaft manually operated by a handle. I

On a recess 39 formed inthe funnel-shaped base 15 is mounted a cylindrical container 40 open at its top and which forms at its upper edge a seat with a flange 41 adapted to receive a second cylindrical container 42 open at its top the perforated bottom 43 of which properly forms a strainer, the lower container40 having a slanting mouth 44 at its front to discharge the strained and stirred milk of the cocoanut, and adjacent to said mouth is placed a straining plate in the shape of a segment 45, so that upon inclining the containers the cocoanut milk coming out through the mouth 44 may be strained again.

On bushings 46 and 47 formed on thebottom of both containers 40 and 42 is rotatorily mounted a vertical shaft 48 which is provided'with' a blade-stirrer 49 within the lower container 40 and said shaft 48 has at its upper end a square-hollow head 50 adapted to couple'withanother solid square head 51, formed at the-lower end of the formed with the horizontal brackets 23 and 24.

For piercing the cocoanut 84 it is provided a piercer 74 (Figs. 4 and 5) which has in its body a hollow space 75 open toward thesides thereof and closed at the bottom by a central protuberance 76 having two opposed curved surfaces slanting toward the sides to serve as a guide outside the cocoanut for the milk pouring by gravity from the cocoanut in its retained position and which passes to the hollow space 75 through a triangular vane '77 laterally formed at the point of the piercer 74.

For cleaning and washing the apparatus, an annular tube provided with lower perforations 56 is arranged in the upper part of'the cover 17 and inside thereof, which is in communication through a tube 5'7 with a water-pipe.

The operation of the apparatusis as follows: a cocoanut 84 is taken and placed vertically with its peduncle connecting end directly above the point of the piercer 74, such as shown by dotted lines in Figure 1 ofthe drawing. Then the horizontal shaft 26 is put into operation by means of any power supplying means, and upon said'shaft 26 is rotating, its motion is transmitted to the vertical shaft 30 by means of the bevelled pinions 27, 28, whereupon the piercer 74 will rotate. Im-

mediately the disc 81 is causedto descend by grasping with the hand the handle and causing the swing-bar 9 to rotate on its horizontal pivots 10, whereupon the hollow columns 4 will slide down uponthe standards 2 until the teeth 82 of the disc 81 pierce upon the cocoanut 84 and retain it in position against rotation. At the same time that the swing-bar 9 descends, the cocoanut 84 is pushed thereby against the point of the rotating piercer 74 and this is introduced into the cocoanut 84 until it takes the position shownin full lines in Fig. 3, whereupon the milk 84' contained in the cocoanut 84 passes out through the triangular vane '77 of the piercer '74 into the hollow space '75 thereof and it is poured by gravity outwardsguided' by the slanting surfaces forming the bottom 76 of said hollow space. The milk of the cocoanut issubsequently re-collected in the upper container 42 through the guiding funnel 55, and it strains through the perforations of bottom 43 and is received in the second container 40 where it is stirred by the blade-stirrer 49. When it is desired to consume the milk of the cocoanut, the detachable half 18 of the cylindrical cover is removed, and by means of the handle 38 the cam 36 is caused to rotate and raise the head 32 of the shaft 30 to disconnect this shaft 30 from the lower shaft 48, whereupon the two containers 42 and 40 can be drawn out. I

Within the lower container 40 crushed ice and 1 sugar may be added to the cocoanut milk, in order to serve it directly to the consumer, once stirred.

What we claim is: i

1. An apparatus for extractingthemilkof a cocoanut which comprises a supporting frame, a vertical shaft rotatorily mounted on said'supporting frame, a piercer detachably mounted on the upper end of said shaft, and which hasa hollow space open at the sides and closed at the bottom by a protuberance having two opposed surfaces slanting toward the sides, and-movable means to cooperate with the piercer to retain the cocoanut against rotation while the cocoanut is pierced by the piercer, said slantingsurfacesof the piercer serving as a guide outside the cocoanut for the milk pouring by gravity from the cocoanut in its retained position.

2. An apparatus for extracting the milk of a cocoanut, whichcomprises a supporting frame, a vertical shaft rotatorily mounted on saidsupporting frame, a piercer which is detach'ably mounted on the upper end of said-shaft and-which has a hollowspace open at thesides to guideoutwards the milk entering through a vane-near-the point of the piercer, -a pair of standards outside the supporting frame and to which thesupporting frame is secured, a pair of" hollow columns connected together at the top by a transversal 'bar and reciprocally mounted on said-standards, a toothed piece mounted at the centerof the transversal bar connecting the reciprocating hollowcolumns to cooperate with the piercer to retain the cocoanut against rotation while; the cocoanut is pierced by thepiercer, and a receiving container placed'below the supporting frame for receiving the cocoanut milk. 9

3. An apparatus for extracting the milk of a cocoanut, which comprises a supporting cover, brackets connected to said cover in horizontal alignment and connected to each other by a casing, a horizontal shaft rotatorily mounted on one of said brackets, a vertical shaft rotatorily and slidably mounted through said casing, bevelled gears within said casing to rotatorily connect both horizontal and vertical shafts, a piercer detachably mounted on the upper end of the vertical shaft and having a hollow space open at the sides to guide outwards the milk entering through a vane adjacent the point of the piercer, a pair of standards outside the cover,- a pair of hollow columns connected together at the top by a transversal bar and reciprocally mounted on said standards, ateethed piece mounted at the center of the top of the transversal bar connecting the reciprocating hollow columns to cooperate with the piercer to retain the cocoanut against rotation while it is pierced and emptied from its milk, a receiving container for the pulp and the milk and another receiving container for the milk alone, the former container being connected to the vertical shaft above mentioned,

and means for rotating said horizontal shaft from any power supplying means.
